ENSILAG-E-PACKING DEVICE.

Application filed July 24, 1922. ,Serial No. 577,095.

To all whom it may concern:

Be it known that we, JOHN E. Damon and SAMUEL M. CnooKsI-IANK, citizens of the -United States, residing at Knoxville, in the county of Knox and State of Tennessee, have invented new and useful Improvements in Ensilage-Packing Devices (Case B), of

which the following is a specification.

This invention relates to improvements in packing machines, especially designed for packing ensilage and is an improvement upon patent numbered 1,328,728, granted to us January 20, 1920.

An object of the present invention is the provision of a machine for packing ensilage within a silo, in which the direction of travel of the machine may be controlled and the pivot shaft or center pole of the above named patent, eliminated, so that thecmachine will be capable of use within silos of different diameters.

Another object of the invention isthe provision of a packing machine of this character having guiding means which may be adj usted and held in adjusted position, whereby the direction of travel of the machine may be slightly changed at intervals, so as to insure uniform packing.

Another object of the invention is the provision of guard rollers so arranged as to engage the walls of a silo and deflect the machine inward when its radius of travel exceeds the radius of the silo, so that injury to either the silo or the machine will be pre: vented.

lVith the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illus trated in the accompanyin drawings and pointed out in the appendec claims.

In the drawings Figure 1 is a top plan view of an ensilage packing machine constructed in accordance with the invention.

Figure 2 is a side view of the same.

Figure 3 is a rear end view.

Figure 4 is an enlarged fragmentary horizontal sectional view on the line 4-1 of Figure 2.

Figure 5 is a detail elevation of the driving gears.

eferring in detail to the drawings, wherein like characters of reference denote corresponding parts, the machine is shown as comprising a frame 10, upon which is mounted a platform 11, the latter being designed to supportthe power mechanism, as will be hereinafter set forth.

Extending downwardly from the frame 110 at each end of the rear of said frame are bearing brackets 12, whose lower ends carry a shaft 18. Mounted upon this shaft are packing rollers 14: and 15, both of said rollers being of frustro-conical shape, the roller 14: being of less diameter than the roller 15, while the peripheries of these rollers are similarly tapered, that is, the angles formed by the sides and ends of the rollers are the same. i The rollers 1d and 15 are spaced apart and mounted upon the, shaft 13 between these rollers is a sprocket wheel 16. This wheel is connected by a chain 17 with a relatively small sprocket wheel 18, the latter being secured upon a shaft 19 which is mounted in bearings supported upon bearing standards 20. The shaft 19 also has secured thereon a spur gear 21, which meshes with a pinion 22 and the latter in turn meshes with a pinion 23 which is secured upon a shaft 24. This last mentioned shaft. is also mounted in bearings supported by the bearing standards 20 and has secured thereon a relatively large sprocket wheel 25. The sprocket wheel 25 is connected to small sprocket wheel 26 by means of a sprocket chain 27, while the sprocket wheel 26 mounted upon the drive shaft 28 of an en-' gine motor 29. It is preferredto equip the machine with an internal combustion engine and for this purpose the machine carries a battery boX 30, which may house a battery for the supply of current to the ignition devices of the engine. The bearing brackets 12 may be braced in any suitable manner, for example, brace rods 31 may connect each of the brackets 12 with the machine frame. The front end of the machine is supported by a combined packing and guide roller This roller is mounted upon a shaft 33 having bearings in a bearing yoke 34. The yoke 34; is connected to the forward end of the frame 10 by means of a king pin 35., which passes through said yoke and through a bearing plate carried by the frame. Connected to the shaft 33 is a guide yoke 36 and the latter has connected thereto as shown at 37,'one end of a guide bar or rod 38. The

I chine'is a bar 42,which-has'one end pivot-' end of a controlling lever 39 which is pivotally mounted as shown at $0 uponabracket The controlling lever 39 passes through an. opening in the platform andmay be pivotally moved to move the 'bearingyoke 34c'upon the" king pin 35, so as to control the direction of travel of the machine. held-in adjusted position by means of a spring actuated latch which engages a toothed segment' ll supported .upon the bracket which supports the lever 39." By this means the guide roller "32 may be set, whereupon the machinewill travel in a circle ,of a given radius and by adjustingthe controlling lever'89 slightly; from time to time; the ensilage or other material being packed by the machine may be evenly packed. Extending from the frame 10 of the maally" secured to said frame and itsopposite end pivotally secured to a controlling lever 43 which extends from the distributing V spout tl of asilo.

The 'machine frame as shown islof substantially triangular form in planandits gage the innerwall of the silo inthe event of the radius of travel of the machine being" greater than the radius of the silo, so that; I injury to either the silo .or the machine, due

inclined edge or hypothenuse is adapted to travel-in-iline with" the circumference of a videsan imaginary pivot about which the machine willtravel. Extending beyond the side of the machine near each end thereof is an 21111145, whose outer end carries a guard roller 46. These rollers are designed to en'- H to contact, will be prevented; 1

Having described the invention what is claimed is 1. A packing machine embodying a frame, a frustro-conical packing rollermounted beneath the frame at one end thereof, means for drivingthe rollerfa combined packing and guide roller mounted beneath the opposite-end of the frame and means forconrection of travel of the machine. 7

2. A packing machine embodying a frame; a frustro-con1cal packing member mounted beneath the frame atone end thereof means for driving the roller, a combined packing and guide roller mounted beneath theop'po- .neath the frame atone end thereof, means for driving the roller, a bearing yoke pivotally mounted beneath the oppositeend ofthe frame; a combined packing and-guide roller mounted'within the yoke and means I connected to theyoke forcontrolling the position of the guide rollerito regulate the'directionof travel ofthe machine. x
